Answer in J.
(10 points)

Answer 1

Answer: 4550 Joules

The formula for potential energy in gravitational field is as follows:

$E_{pot} = mgh=65kg \cdot 10 \frac{N}{kg} \cdot 7m = 4550 J$

Answer 2

Answer:

The gravitational potential  energy the leopard will possess to climbs  7m up is 4550j

Gravitational potential energy is an energy an object possesses because of its position in a gravitational field.

Using the below formula

U = mgh

Where

U = gravitational energy

m = mass

g = acceleration due to gravity

h = height

Given that

mass of leopard = 65kg

height = 7m

g = 10N/kg

U = 65 * 7 * 10

U = 65 * 70

U = 4550J

Hence, the gravitational potential  energy the leopard will possess to climbs  7m up is 4550j
